SSD is non-essential. If you're not running one at the moment, you won't find Windows sluggish. I have a PC that has an SSD and one that just has an HDD - one loads Windows slightly faster and games a couple of seconds faster, but I don't find the difference justifies the cost of an SSD if budget is limited.

16 GB Ram should be the minimum, as others said. You won't be happy with 8 for too long.

As for SSD versus HDD: if you're on budget get a large HDD or even two. SSD ist NOT for data storage, so you'll need a HDD anyways.

If your money is limited I would skip the SSD and invest a bit more into CPU or GPU if possible. Or, if you have kids, get a nice graphics tablet instead.

Whilst I absolutely respect everyone's opinion regarding SSD and HDD and agree that it isn't 'essential' however in my home, I also have 2 PCs with Windows on a SSD and another PC and laptop on HDDs and the difference in my opinion is night and day. For gaming, yes it's no big deal the extra loading times but for general use, everything is significantly slower on a HDD in my experience and for general day to day use, I couldn't recommend ommiting the SSD.

Given the current cost of RAM, your biggest saving will be sticking with 8 GB. Almost all games use a very minimal amount of system RAM - it's the GPUs VRAM that is the major player. System RAM is more for having multiple applications open or multiple browser windows. It really isn't necessary to have 16GB for gaming. You can always drop in another stick of RAM later...

It's highly unlikely you will ever notice or be affected by having only 8GB of RAM compared to 16GB. By having your operating system on a HDD compared to and SSD though, you'll notice it everytime you use your PC.

With all respect...

But RAM is really cheap ATM and really helps the OS with memory management. Of course of you only open one program at the time, 8 GB is really sufficient. ATM.
Regarding SSD the problems are: a) I'ts really only for convenience (although I get understand that when you had it, you don't want to look back) and that's why b) you still need an HDD for storage. And today's HDD are certainly fast enough to enable fluent working and gaming even if they are a lot slower than SSDs.

You may want to take a gander at this video which does some more realistic testing of NVMe SSD vs SATA SSD vs HDD.

A quick look at Amazon.de shows one available DDR4 2*8GB kit for €190 so possible to find under 200. OK risk to buy a single module with 8GB RAM and another later as long as not much later or they might not match. Do not forget to include Windows (if desired) when tallying the costs, it certainly is not free (€100+). Forget an ssd with such a tight budget or learn to live with extremely little space. Maybe you can use the old hdd on the side unless selling the old system.

Windows license is probably present? I don't know how that works nowadays, I have W7 on disk but heard W10 may be tied to the computer?

PS: OP is from Croatia (per forum) so prices may differ. A lot.

How has that CPU been performing for you? What kind of games are you running with it? Just curious if you don't mind me asking.

Really well so far. Helps I still have a 1200p monitor, but I've been running things at pretty much max and getting 60fps. Started with Fallout 4, then played some GTA5, now playing Deus Ex MD. It was a pretty cheap build really, especially since I had a case and whatnot already, and I'm playing quite new games at high settings. I'm happy,

From everything I read the Ryzen has a slight edge for games/software that use more cores while the Intel i5 has a slight edge for the opposite.

Ok, you're right... Wasn't up to date with that. Although for me this still feels cheap... I think I payed about 800 German Mark for 16 MB PC RAM back in the 90s...

Wow!!

My 2 cents…

For most games, quad core is fine. Having a higher core clock speed is preferable to having more cores. Very few games truly take advantage of a heavily-threaded processor (which is why hyperthreading doesn't do much for most games either).

With the games you’ve listed, 8GB RAM should be okay. 16GB gives you room to grow, but I would put that at a lower priority since it’s easy to add more RAM sticks later. Look for a motherboard with 4 memory sockets if possible, so you can take advantage of dual-channel performance with two sticks for now and still have extra slots to expand later without having to toss your existing memory.

The ideal disk configuration is an SSD for the OS, applications and any games which load large chunks of data (such as ultra-high textures) during gameplay; and then a HDD for data (music, photos, docs, etc.) and any other games. If your budget only allows you to pick one or the other, you’ll have to consider the size of your data and games and whether you can fit all that onto an SSD. While there are very large SSDs now, those high capacities quickly become prohibitive to a budget build and it would be more cost effective going back to the hybrid solution of a slightly smaller SSD and a significantly larger HDD.

Graphics card prices are nuts at the moment for both AMD and NVIDIA, though you said you’re wanting to build in July so hopefully things settle down by then. A GTX1060 (or the AMD equivalent -- I think that would be an RX580?) should be able to handle all those games you’ve listed at a 1920x1080 resolution.

Curious.

How do games, the majority of which are 32 bit applications, require anything like 16GB?

There's a distinct trend in newer games of the last couple of years being 64-bit only, and this is only going to increase going forward, including higher RAM requirements.
